COMBINED STOVE-PIPE HEATER AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 395,999, dated January 8, 1889. A lication fil d Tune 29, 1888. Serial No. 278,514. (No model.)

To. aZZ whom it may concern:

Be it known that I, ALEXIS HAROLD Ross, of lVaukon, in the county of Allamakee and State of Iowa, have invented certain new and useful Improvements in a Combined Stove- Pipe Heater and Ventilator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in a combined stove-pipe heater and ventilator; and the objects of my invention are to form in the lower part of the heater an air-chamber, into which the air is admitted, and which then escapes through the vertical pipes, which are heated by the escaping products of combustion; to place inside of the heater a hotair chamber and deflector, which is connected at its lower end with the air-chamber inside of the heater, and is provided at its upper end with pipes for the escape of the heated air, and to connect to the heater a ventilatingpipe which will take all of the foul air from the bottom of the room and discharge it directly into the stove-pipe.

Figures 1. and 2 represent vertical sections of a device embodying my invention, taken at right angles to each other.

A represents the stove-pipe, and B the heater, which is placed between the two sections of the pipe A, and through which heater all the products of combustion must pass. In the lower end of this heater B is formed an air-chamber, U, and to this chamber is connected, at one side, the air-pipe D, which is provided with a register, E, and a damper, F. The lower end of this pipe I) is to be made to extend to the outside air, so that when the damper 1* is open and the register E is closed pure air will be admitted to the chamber (7, heated, and then discharged into the room. Should heat more than fresh air be desirable, as in very cold weather, the damper F will be closed and the register E opened, and then the cool air will be taken from the bottom of the room, heated, and discharged back into the upper part of the room. \Vhen the damper F is open, the register E should be closed, and when the register is open the damper should be closed. The air admitted to the chamber 0 rises through the pipes G, in which it is heated, and escapes from the pipes into the top of the room.

Placed inside of the heater B is a hot-air chamber and deflector, H, which is located directly in the line of the upward passage of the products of combustion, and which serves to deflect the products outward toward the sides of the heater B and around the pipes G. The heater B throws off its heat into the room and the pipes Gabsorb a great portion of the escaping heat and utilizes it in heating the air which is passing through them. lVere it not for this chamber H the products of combustion would pass directly through the heater B, and then the greater portion would be allowed to escape up the chimney. Connected to the lower end of this chamber H and to the top of the chamber 0 are the pipes G, through which a portion of the air admitted into the chamber 0 passes into the chamber H to be heated, and from the top of which chamber H this heated air escapes through the pipes J into the top of the room.

Extending upward from the bottom of the room and connected with the upper end of the heater 15 is the pipe L, which is provided with the damper O. \Vhen the damper O is opened, the foul air in the room is taken through the lower' end of the pipe L, discharged directlyinto the upper portion of the heater B, and from thence it is discharged into the stove-pipe. This pipe L is connected to the upper end of the heater 1%, so that the cold air which is being taken from the bottom of the room will not serve to diminish the amount of heat which is being absorbed by the pipes (i, G, and J and the chambers C H, as would otherwise be the case if the pipe L were connected to the heater near its bottom. Being connected to its top, the cold air from the bottom of the room is discharged into the heater at that point where the heat is no longer exerting any great amount of effect.

It will be seen from the construction here shown and described that this heater can be made to take the place of a stove where only a moderate amount of heat is necessary, and in the eenter of the heater and provided with can be made both to heat; and to ventilate :1 the pipes G J,:1nd which ,+h:1mber 11 receives room moSt perfectly. its air from the ehnmber t, substzrntinity as Having thus deseribed my iiwention, I described. 5 eiaim In testimoirv whereof I affix my signature 15 The combination of the stove-pipe, the airi in prwenee of two witnesses. chamber located in its lower end, the pipe for ALEXIS II'ARO'L'I) ROSS. admitting air to this chamber, the pipes (t, which extend from the top of the ehmnber \Y i tnesses:
